Quick Answer: The Yarbo M Series is a second, cheaper modular yard-robot line from Yarbo — smaller tracked bases (M10, M20, M20i) that swap between mowing, snow-blowing and leaf-clearing modules, plus a patrol/follow-me Smart Assist Module. It raised $3,638,573 from 850 backers on Kickstarter (campaign closed April 20, 2026) against an estimated August 2026 ship date, per Kickstarter’s own campaign reporting — but as of September 2026 there’s still no fixed retail price or confirmed on-time delivery, and Yarbo’s own backer forum shows users questioning whether shipping slips into 2027. If you want a working modular yard robot today, Yarbo’s original Lawn Mower Pro Core ($5,999) is already retail; the M Series is not yet a same-day purchase.
Yarbo already sells one modular yard robot — the Core-based Lawn Mower/Lawn Mower Pro system we cover in our full Yarbo review. The M Series is a distinct, smaller, cheaper attempt at the same idea, and it’s important not to confuse the two: one is a settled $4,999-$5,999 retail product, the other is still a crowdfunded campaign working through fulfillment.
What the M Series actually is
Per Kickstarter’s own campaign page and CES 2026 coverage, the M Series is built around a single tracked “core” robot that accepts interchangeable modules — mirroring the original Yarbo’s pitch, just at a smaller scale and lower price point. Three core trims were offered:
| Model | Coverage | Motors | Battery | Notable |
|---|---|---|---|---|
| M10 | Up to 1 acre/day | 150W x2 | 10Ah | Razor-blade cutting, entry trim |
| M20 | Up to 1.5 acres/day | 300W x2 | 20Ah | Straight-blade cutting |
| M20i | Up to 1.5 acres/day | 300W x2 | 20Ah | Adds LiDAR + RTK for complex/shaded yards, night operation |
Attachable modules include the M1 mowing deck, an S1 snow blower, and a B1 leaf blower, per Kickstarter reporting. Yarbo later added a fourth option mid-campaign: the Smart Assist Module (SAM), which lets the bare tracked core patrol a property or follow a person at roughly 2-5 meters and tow up to 100kg — priced at $199 early-bird against a stated future MSRP of $249.
Funded fast, but the ship date is already in question
The campaign launched March 4, 2026 and reportedly crossed $1 million in pledges within two hours from over 200 backers, eventually closing April 20, 2026 at $3,638,573 from 850 backers — a genuinely large crowdfunding result for a yard-care product. The stated estimate was August 2026 delivery.
That’s where the confirmed facts stop. Yarbo’s own community forum now hosts threads on both a post-campaign $50 refundable reservation (for buyers who missed the original window, which itself signals the initial campaign’s units are spoken for) and open skepticism from backers about the August date — one forum participant predicts a slip to “spring of ‘27,” and separate threads note conflicting shipping-window language (“some pages/ads say February while others say March”) for the next order wave. None of that is an official delay announcement from Yarbo, but it’s a real signal that the August 2026 estimate shouldn’t be treated as settled.

- Same hot-swap module philosophy — mow, blow snow, clear leaves — but on hardware that's been shipping and supported since 2026, not a Kickstarter estimate.
- RTK-vision navigation with no boundary wire and no subscription fee, per Yarbo.
- A normal purchase with a standard warranty today, versus a pledge with an unconfirmed delivery window.

Yarbo M Series by the numbers
- $3,638,573: Total raised from 850 backers on Kickstarter, per the campaign’s own final tally — one of the larger yard-robotics crowdfunds of 2026.
- August 2026: The campaign’s original estimated ship date; as of this September 2026 writing, backer-forum discussion questions whether it will hold, with one estimate pointing to spring 2027.
- $199 → $249: The Smart Assist Module’s Kickstarter early-bird price versus its stated future MSRP — a $50 gap typical of this campaign’s backer-discount structure.
- 1.5 acres/day: Yarbo’s claimed coverage rate for the higher-tier M20/M20i trims, versus 1 acre/day for the entry M10.
The bottom line
The Yarbo M Series is a real, well-funded product — $3.6 million from 850 backers isn’t vaporware-tier interest — but it is not yet a retail purchase. No fixed MSRP exists, and Yarbo’s own community is openly unsure the August 2026 ship estimate will hold. If the modular mow/snow/leaves concept is what draws you in, Yarbo’s original Lawn Mower Pro Core already delivers that today at a settled $5,999 price.
